7202LA30DB

Overview

The Renesas 7202LA30DB is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It features a unidirectional bus architecture and supports data rates up to 25MHz with a maximum access time of 30ns. The component operates on a single 5.0V supply voltage within the range of 4.5V to 5.5V. It is housed in a 28-pin CDIP package and is designed for high-speed buffering applications requiring reliable data transfer between asynchronous clock domains.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Uni-directional bus interface for streamlined data flow management
• High-speed performance with ultra-fast access times for efficient buffering

Applications

• Data buffering between asynchronous clock domains
• Interface bridging in high-speed digital systems
• Temporary data storage in communication protocols

Procurement Notes

Verify the specific package type and pinout configuration against your schematic, as variations exist within the 7202 family. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for obsolescence notices or replacement part recommendations from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a unidirectional asynchronous FIFO with 9-bit word width is required. Ensure the 30ns access time meets your system's timing constraints. Verify that the 28-pin CDIP package fits your board layout and that the operating temperature range aligns with your environmental specifications.
